Description

  The present invention relates to a paper sheet storage and feeding device that stores and feeds paper sheets by winding and rewinding a tape.

  2. Description of the Related Art Conventionally, for example, in a banknote depositing / dispensing machine for depositing / withdrawing banknotes as paper sheets, a tape storing type banknote storing and feeding device using two or one tape for storing and feeding banknotes. There is something with.

  In a bill storage and feeding device using two tapes, a bill is fed between two tapes taken up on a take-up drum so that the bills are taken up and stored together with the two tapes on a take-up drum. Yes. On the other hand, by rewinding two tapes from the take-up drum, a bill is fed out between the two rewinded tapes (see, for example, Patent Document 1).

  Moreover, in the banknote storing and feeding apparatus using one tape, the banknote is fed together with one tape by feeding the banknote between one tape wound around the winding drum and the outer peripheral surface of the winding drum. Is wound around a take-up drum and stored. On the other hand, by rewinding one tape from the take-up drum, the banknotes are fed out between the one rewind tape and the outer peripheral surface of the take-up drum (for example, see Patent Document 2).

  In such a tape storage type banknote storage and feeding device, the length of the tape is limited, and there is an end of the tape to be rewound from the take-up drum and an end position of the tape to be taken up by the take-up drum. It is necessary to stop the rewinding and winding of the tape at the end of the tape.

  In order to detect the end of the tape, for example, use a tape in which the end side of the tape is transparent, the other is opaque, and the boundary between the transparent part and the opaque part is the end detection position. In this case, an end detection unit that is an optical sensor that projects and receives detection light is used. For example, when the tape is rewound from the take-up drum, the transparent portion of the tape moves to the position of the end detection unit, and the amount of transmitted light detected by the end detection unit becomes larger than a predetermined value. The detection position is detected.

  In the bill storage and feeding device, the rotation amount of the take-up drum and the roller for guiding the tape to the take-up drum are used for the purpose of controlling the feeding speed of the tape and detecting the length of the bill taken up on the take-up drum. A rotary encoder that detects the amount of rotation is used.

  However, in the conventional bill storage / delivery device, the rotary encoder is used for the amount of rotation of the winding drum or roller, but the end detection position of the tape is detected by only one end detection unit. Therefore, if dust or the like adheres to the sensor part that projects and detects the detection light of the end detection unit and the detection light is blocked, or if a failure occurs in the end detection unit due to a failure of the end detection unit, etc. The end detection position cannot be detected.

If the tape end detection position cannot be detected in this way, for example, when the take-up drum rotates in the rewind direction and the tape is rewound from the take-up drum, the rewind from the take-up drum is performed. Even when the tape being reached reaches the end detection position, the take-up drum continues to rotate in the rewind direction, so that the take-up drum winds the tape in the opposite direction. When such an abnormal state occurs, there is a problem that the recovery cannot be easily performed or the tape is cut in some cases.

Transport and withdraw.

  Next, a banknote storage and feeding device 19 is shown in FIGS.

  The banknote storage and feeding device 19 includes a frame body 31 attached to the banknote handling machine 11. A winding drum 35 in which a drum attachment end, which is one end of two tapes 33, 34, is attached to the frame 31 as a paper inlet / outlet 32 as a paper sheet entry / exit facing the conveyance path 17, and each tape. Two take-up reels 36 and 37 each having a reel attachment end, which is the other end of 33 and 34, guide rollers 38 and 39 for guiding the tapes 33 and 34 at positions facing the banknote slot 32, and Guide rollers 40 and 41 for guiding the tapes 33 and 34 are disposed between the take-up reels 36 and 37 and the guide rollers 38 and 39, respectively.

  The banknote entry / exit 32 allows receipt of a banknote 42 as a paper sheet conveyed from the conveyance path 17 and delivery of the banknote 42 to the conveyance path 17. When the banknote 42 is stored, the banknote 42 received from the banknote inlet / outlet 32 is sandwiched between the tapes 33 and 34 by winding the both tapes 33 and 34 onto the winding drum 35 and is wound and stored. Further, when the banknote 42 is fed out, the banknote 42 is fed out toward the banknote entrance / exit 32 by rewinding both the tapes 33 and 34 from the winding drum 35. The direction in which the banknotes 42 are stored and fed out by the banknote storage and feeding device 19 is the short direction of the banknotes 42.

  A bill detection sensor 45 for detecting the bill 42 passing for storage and feeding is disposed at the bill insertion / extraction port 32.

  Each tape 33, 34 has a width narrower than that of the banknote 42, for example, about 1/3 of the length of the banknote 42 in the longitudinal direction. Each of the tapes 33 and 34 is made of, for example, polyethylene terephthalate as a tape material, and a part of the surface of the tape material is coated with an opaque material or the like.

  Ends (actual end positions) of the tapes 33 and 34 to be rewound from the take-up drum 35 (actual end positions), and end points on the reel attachment end side of the tapes 33 and 34 to be wound around the take-up drum 35 (actual end points) Position) can be detected by distinguishing between end regions 33a, 34a of a predetermined length at both ends of each tape 33, 34 and central regions 33b, 34b between these end regions 33a, 34a. It has become. For example, the end regions 33a and 34a are transparent, the central regions 33b and 34b are opaque, and the transparent central portions 33b and 34b of the tape material are coated with an opaque material or the central regions 33b and 34b are formed. The transparent tape material which comprises the edge part areas 33a and 34a is couple | bonded with the both ends of the opaque tape material to perform. End detection marks 33c and 34c in which the boundary portion between the transparent portion of the end regions 33a and 34a and the opaque portion of the central regions 33b and 34b indicate the end detection position before the actual end position of the tapes 33 and 34; It has become. The end regions 33a and 34a are transparent and the central regions 33b and 34b are opaque. However, the transparency and opaqueness may be reversed, or may be translucent if there is a difference in the amount of light transmission. .

  Between the guide rollers 38 and 39 and the guide rollers 40 and 41, the end detection marks 33c and 34c of the tapes 33 and 34 are detected, and are rewinded from the winding drum 35, or are wound on the winding drum 35. End detection units 46 and 47 for detecting the end detection position before the actual end position of the winding tapes 33 and 34 are arranged. Each end detection unit 46, 47 uses an optical sensor that projects and receives detection light between the light projecting unit and the light receiving unit with the tapes 33, 34 interposed therebetween.

  The take-up drum 35 is attached to a take-up drum shaft 50 that is rotatably supported by the frame 31.

  The take-up reels 36 and 37 are hooked reels having hooks on both sides, and are attached to the take-up reel shafts 51 and 52 supported by the frame body 31 via torque limiters 53 and 54. The take-up reel shafts 51 and 52 correspond to the tape take-up direction (the clockwise direction in FIGS. 1 and 2) of the take-up reels 36 and 37 by a one-way clutch (not shown) interposed between the take-up reel shafts 51 and 52. Rotation is allowed only in the direction, and rotation in the direction corresponding to the tape unwinding direction (counterclockwise direction in FIGS. 1 and 2) of each take-up reel 36, 37 is prevented.

  The guide rollers 38 and 39 and the guide rollers 40 and 41 can guide the tapes 33 and 34, and may be rotatably attached to the frame 31 or may be fixed.

  A motor 57 is disposed between the winding drum 35 and the winding reels 36 and 37. A pulley 58 is attached to the end of the drive shaft of the motor 57, a large-diameter pulley 59 is attached to the end of the take-up drum shaft 50, and a one-way clutch (not shown) is attached to the end of each take-up reel shaft 51, 52. Small-diameter pulleys 60 and 61 are attached. An endless belt 62 is wound around the pulleys 58 to 61, and the belt 62 is rotated by forward and reverse rotation driving of the motor 57, whereby the pulleys 58 to 61 are rotated.

  In this case, the take-up reel shafts 51 and 52 are rotated from the pulleys 60 and 61 only in the direction corresponding to the tape take-up direction (the clockwise direction in FIGS. 1 and 2) of the take-up reels 36 and 37 by the one-way clutch. The driving force is transmitted and rotates in the same direction, and the rotational driving force is applied from the pulleys 60 and 61 in the direction corresponding to the tape rewind direction (counterclockwise direction in FIGS. 1 and 2) of the take-up reels 36 and 37. Not transmitted.

  In addition, each take-up reel shaft 51, 52 has a diameter difference between the pulley 59 of the take-up drum shaft 50 and the pulleys 60, 61 of each take-up reel shaft 51, 52, regardless of the take-up amount of the tape 33, 34. The winding speed of the take-up reels 36 and 37 including the tapes 33 and 34 is rotated at a rotational speed that is always higher than the peripheral speed of the take-up drum 35 including the tapes 33 and 34.

  One take-up reel 36 is connected to a rotary encoder 65 as a rotation amount detection unit that detects the rotation amount of the take-up reel 36. Here, the rotary encoder 65 is connected to the take-up reel 36 via a roller that rotates in contact with the flange of the take-up reel 36, but the rotation amount of the take-up reel 36 may be detected by other methods.

  Moreover, the control part 71 which controls the banknote storage and feeding apparatus 19 is shown in FIG.

  The control unit 71 inputs signals from the banknote detection sensor 45, the end detection units 46 and 47, the rotary encoder 65, and the like, and controls the motor 57. The control unit 71 can communicate with a higher-level control unit included in the banknote handling machine 11, or the control unit 71 itself is configured as a control unit of the banknote handling machine 11. Further, the control unit 71 includes a ROM 72 and a RAM 73 that store programs and various data.

  The control unit 71 determines the amount of movement of the tapes 33 and 34 between the winding drum 35 and the winding reels 36 and 37 from the diameter of the core of the winding reel 36, the thickness of the tape 33, and the output of the rotary encoder 65. It has a function of the tape movement amount detection unit 74 to detect. More specifically, the diameter D [mm] of the core of the take-up reel 36, the thickness T [mm] of the tape 33, and the rotation amount n [rotation] of the take-up reel 36 from the position where the tapes 33 and 34 are not wound. Then, the diameter of the take-up reel 36 on which the tape 33 is wound is obtained, and the moving amount of the tape 33 is obtained from this diameter and the rotation amount of the take-up reel 36. That is, the diameter of the take-up reel 36 after n rotations is D + 2nT [mm]. At this time, when the take-up reel 36 makes one rotation, the tape 33 moves by π (D + 2nT) [mm].

  In this tape movement amount detection unit 74, the end detection positions detected by the end detection units 46 and 47 on the end detection marks 33c and 34c on the drum mounting end side of the tapes 33 and 34 to be rewound from the take-up drum 35 are the reference positions. As a result, the amount of movement of the tapes 33 and 34 is detected. For example, as shown in FIG. 4, the end detection position detected by the end detection unit 46 at the end detection mark 33c on the drum mounting end side of the tape 33 is set to the reference position 0, and the tape 33 is being moved in the winding direction. Counts +1 for each predetermined distance, and counts -1 for each predetermined distance during movement in the direction of rewinding the tape 33. Further, the tape movement amount detection unit 74 resets to the reference position every time the end detection unit 46 detects the end detection mark 33c on the drum attachment end side of the tape 33 to be rewound from the take-up drum 35.

  Further, the control unit 71 can detect the end region on the drum mounting end side of the tapes 33 and 34 to be rewound from the take-up drum 35 based on the movement amounts of the tapes 33 and 34 detected by the tape movement amount detection unit 74. It has the function of the termination | terminus area | region detection part 75. In addition, the termination region detection unit 75 can also detect the termination region on the reel attachment end side of the tapes 33 and 34 to be rewound from the take-up reels 36 and 37, respectively. The end regions of these tapes 33 and 34 are regions set between the actual end position and the end detection position (end detection marks 33c and 34c), and are set at an appropriate distance from the end detection position. This is an area from the start position of the area to the actual end position.

  In the end region detection unit 75, after the end detection units 46 and 47 detect the end detection marks 33c and 34c on the drum mounting end side of the tapes 33 and 34 to be rewound from the take-up drum 35, The end area is set to be detectable. For example, in the example shown in FIG. 4, the position of −10 moved in the direction of rewinding the tape 33 from the reference position 0 which is the end detection position where the end detection mark 33c on the drum mounting end side of the tape 33 is detected. Set to the start position of the end region. Similarly, in the end region detection unit 75, after the end detection units 46 and 47 detect the end detection position on the reel mounting end side of the tapes 33 and 34 to be rewound from the take-up reels 36 and 37, the reel mounting end is detected. It is set to be able to detect the end region on the part side.

  The termination region needs to be set appropriately in consideration of the following. That is, if the start position of the end area is close to the actual end position, and the winding drum 35 is manually rotated when the rotary encoder 65 is not operating, the actual end position is detected before the end area is detected. May come. Conversely, when the start position of the end region is close to the end detection position, if the winding drum 35 is manually rotated when the rotary encoder 65 is not operating, the end region is detected before the end detection position is detected. Has been doing. That is, it is necessary to set the start position of the end region with a margin in case the winding drum 35 is manually rotated.

  Therefore, for example, the start position of the termination region is set to an intermediate position between the termination detection position and the actual termination position, or 1/3 to 2/3 between the termination detection position and the actual termination position. Movement of the tapes 33 and 34 when the winding drum 35 is rotated a predetermined number of times (for example, twice) by setting the range position or the distance from the start position of the end area to the end detection position or the actual end position. It is set as appropriate with a margin in case the winding drum 35 is manually rotated, such as to make it more than the amount.

  When the motor 57 is driven, if the control unit 71 detects any one of the termination detection units 46 and 47 and the termination region detection unit 75, the control unit 71 stops the motor 57, and the termination region detection unit 75 detects the termination region. When detected, it has a function of determining that the end detection units 46 and 47 are abnormal.

  Further, the control unit 71 moves the tapes 33 and 34 between the winding drum 35 and the winding reels 36 and 37 from the diameter of the core of the winding reel 36, the thickness of the tape 33, and the output of the rotary encoder 65. It has a function of detecting the speed and controlling the motor 57. For this detection function, the diameter of the take-up reel 36 that has taken up the tape 33 is obtained from the diameter of the core of the take-up reel 36, the thickness of the tape 33, and the amount of rotation of the take-up reel 36. The moving speed of the tape 33 is obtained from the rotation amount of the reel 36, and is the same as the function of the tape moving amount detection unit 74.

  Next, the operation of the bill storage / delivery device 19 will be described.

  First, the operation during bill storage will be described.

  In the storage standby state in which the banknote 42 is not stored, the tapes 33 and 34 are rewound from the take-up drum 35. For example, the end detection units 46 and 47 detect the end of the tapes 33 and 34 on the drum mounting end side. The terminal detection marks 33c and 34c that are positions are detected.

  Then, when the banknote 42 is transported from the transport path 17 to the banknote storage and feeding device 19, the motor 57 corresponds to the banknote storage direction by detecting the banknote 42 with a sensor (not shown) provided in the transport path 17. Rotate in the direction.

  As a result, the take-up drum 35 rotates in the tape take-up direction (counterclockwise direction in FIGS. 1 and 2) via the belt 62 and the pulley 59, and the take-up drum 35 starts to take up the tapes 33 and 34.

  On the other hand, the pulleys 60 and 61 are also rotated via the belt 62, but the rotational driving force is not transmitted to the take-up reel shafts 51 and 52 by the one-way clutch, and the take-up reel shafts 51 and 52 are taken up by the take-up reels 36 and 37. It does not rotate in the direction corresponding to the tape unwinding direction. Further, since the take-up reel shafts 51 and 52 are prevented from rotating in a direction corresponding to the tape rewind direction from the take-up reels 36 and 37 by the one-way clutch, the take-up reel shafts 51 and 52 are connected to the torque limiter. The take-up reels 36 and 37 attached via 53 and 54 do not rotate in the tape rewind direction. Therefore, tension is applied to the tapes 33 and 34 wound around the winding drum 35. When the tension applied to the tapes 33 and 34 becomes larger than the set torque value of the torque limiters 53 and 54, the torque limiters 53 and 54 slip and the take-up reels 36 and 37 rotate in the tape rewind direction. Therefore, the tapes 33 and 34 are wound on the winding drum 35 with a certain tension applied.

  At this time, the moving speed of the tapes 33 and 34 is detected from the amount of rotation of the take-up reel 36 detected by the rotary encoder 65, and the motor 57 is controlled so that the moving speed of the tapes 33 and 34 is constant.

  And the banknote 42 conveyed to the banknote inlet / outlet 32 from the conveyance path 17 is pinched | interposed between the tapes 33 and 34, and this banknote 42 is wound up and accommodated in the winding drum 35 with tapes 33 and 34. FIG.

  At this time, the rotary encoder 65 detects the rotation amount of the take-up reel 36, and the tape movement amount detection unit 74 detects the movement amounts of the tapes 33 and 34.

  The banknote 42 is wound based on the detection of the banknote detection sensor 45 that detects the passage of the banknote 42 being wound and stored on the winding drum 35 and the movement amount detection of the tapes 33 and 34 by the tape movement amount detection unit 74. The motor 57 is stopped at a predetermined timing to be taken up by the take-up drum 35, and the take-up of the tapes 33 and 34 by the take-up drum 35 and the rewind of the tapes 33 and 34 from the take-up reels 36 and 37 are stopped. The storage of the banknotes 42 is completed.

  Further, when storing a plurality of banknotes 42, such storing operation is repeated continuously.

  The banknotes that can be stored by being wound around the take-up drum 35 by the banknote storage and feeding device 19 from the maximum number of banknotes 42 that are stored in the banknote storage and feeding device 19 (for example, the number of banknotes 42 that can be inserted into the deposit port 15). The number of 42 is set more. Therefore, normally, a plurality of banknotes are detected without the end detection units 46, 47 detecting the end detection marks 33c, 34c on the reel mounting end side of the tapes 33, 34 that are rewound from the take-up reels 36, 37. When the storage of 42 is completed, the winding of the tapes 33 and 34 by the winding drum 35 and the rewinding of the tapes 33 and 34 from the winding reels 36 and 37 are stopped.

  Next, the operation | movement at the time of banknote delivery is demonstrated with reference to the flowchart of FIG.

  In response to the feeding command, the motor 57 is rotationally driven in a direction corresponding to the bill feeding direction (step 1).

  As a result, the take-up drum 35 rotates in the tape rewind direction via the belt 62 and the pulley 59, and the tapes 33 and 34 start to be rewound from the take-up drum 35.

  On the other hand, the take-up reel shafts 51 and 52 rotate in a direction corresponding to the tape take-up direction by the take-up reels 36 and 37 via the belt 62, the pulleys 60 and 61, and the one-way clutch. At this time, the one-way clutch allows the take-up reel shafts 51 and 52 to rotate in a direction corresponding to the tape take-up direction by the take-up reels 36 and 37. As the take-up reel shafts 51 and 52 rotate, the take-up reels 36 and 37 rotate in the tape take-up direction via the torque limiters 53 and 54, and the take-up reels 36 and 37 take up the tapes 33 and 34, respectively.

  From the relationship of the diameter ratio between the pulleys 60 and 61 of the take-up reel shafts 51 and 52 and the pulley 59 of the take-up drum shaft 50, the take-up reels 36 and 37 of the take-up reel shafts 51 and 52 are Since it rotates at a higher peripheral speed than the take-up drum 35, the tape take-up speed by the take-up reels 36 and 37 is the winding speed regardless of the tape take-up amount ratio between the take-up reels 36 and 37 and the take-up drum 35. It becomes faster than the tape rewinding speed from the take-up drum 35, and tension is applied to the tapes 33, 34 taken up by the take-up reels 36, 37.

  When the tension applied to the tapes 33 and 34 becomes larger than the set torque value of the torque limiters 53 and 54, the torque limiters 53 and 54 slip, and the take-up reels 36 and 37 take up the take-up reel shaft 51 in a state where a constant torque is applied. , Rotate in the same tape winding direction at a speed slower than 52. Therefore, the tapes 33 and 34 are wound around the take-up reels 36 and 37 with a certain tension applied.

  At this time, the moving speed of the tapes 33 and 34 is detected from the amount of rotation of the take-up reel 36 detected by the rotary encoder 65, and the motor 57 is controlled so that the moving speed of the tapes 33 and 34 is constant.

  The banknotes 42 are rewound together with the tapes 33 and 34 by rewinding the tapes 33 and 34 from the winding drum 35. The banknote 42 rewound from the winding drum 35 is fed out between the tapes 33 and 34 to the transport path 17 through the banknote inlet / outlet 32.

  After the banknote detection sensor 45 detects that the last stored banknote 42 has been fed out, the end detection units 46 and 47 are the end detection positions on the drum mounting end side of the tape 33. The marks 33c and 34c are detected (YES in step 2). By this detection, the motor 57 is stopped (step 4), the rewinding of the tapes 33 and 34 from the winding drum 35 and the winding of the tapes 33 and 34 by the winding reels 36 and 37 are stopped, and the initial storage standby is performed. Return to the state.

  Further, when there is a problem with the rotary encoder 65, the abnormality of the rotary encoder 65 can be determined from the output of the rotary encoder 65 when the take-up reel 36 is rotating during bill storage or bill feeding.

  On the other hand, if the end detection units 46, 47 are defective due to dust adhering to the sensor portions of the end detection units 46, 47 and blocking the detection light, or due to a failure of the end detection units 46, 47, etc. Unless the end detection marks 33c and 34c of the tapes 33 and 34 are detected, the abnormality of the end detection units 46 and 47 cannot be determined.

  Therefore, when a failure occurs in the end detection units 46 and 47 during bill feeding, the end detection marks 33c and 34c on the drum mounting end side of the tapes 33 and 34 reach the positions of the end detection units 46 and 47. However, this cannot be detected (NO in step 2), and the rewinding of the tapes 33 and 34 from the winding drum 35 and the winding of the tapes 33 and 34 by the winding reels 36 and 37 are continued.

  In this case, before reaching the actual end position of the tapes 33 and 34 to be rewound from the take-up drum 35, the end region detection unit 75 sets the movement amount of the tapes 33 and 34 detected by the tape movement amount detection unit 74. Based on this, it is detected that the positions of the tapes 33 and 34 are within the end region on the drum mounting end side (YES in step 3). For example, in the example shown in FIG. 4, the end detection position detected by the end detection unit 46 at the end detection mark 33c on the drum mounting end side of the tape 33 is moved to the reference position 0, and the tape 33 is moved in the direction of rewinding. When the position of is the start position of the end region, it is detected that the position of −10 of the tape 33 is within the end region when it has moved to the position of the end detection unit 46.

  When the end region is detected by the end region detecting unit 75, the motor 57 is stopped (step 5), the tapes 33 and 34 are rewound from the take-up drum 35, and the tapes 33 and 34 are taken up by the take-up reels 36 and 37. To stop. At the same time, it is determined that the end detection units 46 and 47 are abnormal, and abnormal processing such as outputting abnormality information to a higher-level control unit of the banknote handling machine 11 or notifying the abnormality on the display unit of the banknote handling machine 11 is performed. (Step 6).

  As described above, even if the end detection portions 46 and 47 cannot detect the end detection marks 33c and 34c on the drum mounting end side of the tapes 33 and 34 to be rewound from the take-up drum 35, the tapes 33 and 34 are detected. Since the end region detector 75 can detect the end region of the tape 33, the end of the tape 33, 34 can be detected reliably. Therefore, before the tapes 33 and 34 to be rewound from the take-up drum 35 reach the actual end positions, the tapes 33 and 34 are rewound from the take-up drum 35 and the tapes 33 and 34 by the take-up reels 36 and 37 are used. Can be stopped, and the occurrence of a problem that the winding drum 35 winds the tapes 33 and 34 in the direction opposite to the normal direction can be prevented.

  Further, the end detection marks 33c and 34c of the tapes 33 and 34 to be rewound from the take-up drum 35 are detected at the end, based on the timing at which the end area detection unit 75 detects the end areas of the tapes 33 and 34 to be rewound from the take-up drum 35. Since the timing detected by the units 46 and 47 is set first, when the termination region detection unit 75 detects the termination region, it is certain that an abnormality has occurred in the termination detection units 46 and 47. Can be determined.

  Further, the start position of the termination area detected by the termination area detection unit 75 is set to, for example, an intermediate position between the termination detection position and the actual termination position, or between the termination detection position and the actual termination position. The position is set within a range of 1/3 to 2/3, or the winding drum 35 is rotated a predetermined number of times (for example, twice) for the distance from the start position of the end region to the end detection position or the actual end position. For example, the amount of movement of the tapes 33 and 34 may be set to be larger than that when the winding drum 35 is manually rotated. Therefore, when the rotary encoder 65 is not operated to eliminate a detection error by the tape movement amount detection unit 74 or a banknote jam, the winding drum 35 is manually rotated in either the rewinding direction or the winding direction. Even if the end region of the tapes 33 and 34 to be rewound from the take-up drum 35 is before the end detection position, it may be erroneously determined that an error has occurred in the end detection units 46 and 47, or the end region It is possible to prevent the start position from exceeding the actual end position.

  The tape movement amount detection unit 74 is based on the end detection position detected by the end detection units 46 and 47 on the end detection marks 33c and 34c on the drum mounting end side of the tapes 33 and 34 to be rewound from the take-up drum 35. Since the amount of movement of the tapes 33 and 34 is detected as the position, the end regions of the tapes 33 and 34 can be reliably detected.

  Further, the tape movement amount detection unit 74 is detected each time the end detection units 46 and 47 detect the end detection marks 33c and 34c on the drum mounting end side of the tapes 33 and 34 to be rewound from the take-up drum 35. Is reset to 0, the detection error by the tape movement amount detection unit 74 can be corrected.

  Further, the tape movement amount detection unit 74 detects the movement amount of the tapes 33 and 34 from the rotation amount of the take-up reel 36, for example, when detecting the movement amount of the tapes 33 and 34 from the rotation amount of the take-up drum 35. The amount of movement of the tapes 33 and 34 can be accurately detected without being affected by the thickness of the banknote 42.

  Similarly, in order to detect the moving speed of the tapes 33 and 34 from the rotation amount of the take-up reel 36, for example, the thickness of the banknote 42 when detecting the movement amount of the tapes 33 and 34 from the rotation amount of the take-up drum 35 is used. It is possible to accurately detect the moving speed of the tapes 33 and 34 without being affected by the above. Therefore, the moving speed of the tapes 33 and 34 can be made constant, the bill 42 can be stored and fed out stably, the skew and deformation of the bill 42 can be prevented, and the occurrence of the clogging of the bill 42 can be reduced.

  As described above, when the banknotes are stored, the maximum number of banknotes 42 stored in the banknote storage and delivery device 19 (the number of banknotes 42 that can be inserted into the deposit port 15) is taken up by the banknote storage and delivery device 19. The number of banknotes 42 that can be wound around 35 and stored is set larger. Therefore, normally, a plurality of banknotes are detected without the end detection portions 46, 47 detecting the end detection marks 33a, 34a on the reel mounting end side of the tapes 33, 34 that are rewound from the take-up reels 36, 37. 42, the winding of the tapes 33 and 34 by the winding drum 35 and the rewinding of the tapes 33 and 34 from the winding reels 36 and 37 are stopped. When the number of banknotes stored is large, the end detection marks 33a, 34a on the reel mounting end side of the tapes 33, 34 rewound from the take-up reels 36, 37 are used as the end detection units 46, 47. Is assumed to be detected.

  In such a case, if the end detection units 46 and 47 detect the end detection marks 33c and 34c on the reel mounting end side of the tapes 33 and 34, the motor 57 is stopped and the tapes 33 and 34 by the winding drum 35 are stopped. And the rewinding of the tapes 33 and 34 from the take-up reels 36 and 37 are stopped.

  At this time, if a failure occurs in the end detection units 46 and 47, even if the end detection marks 33c and 34c on the reel mounting end side of the tapes 33 and 34 reach the position of the end detection units 46 and 47, This cannot be detected, and the winding of the tapes 33 and 34 by the winding drum 35 and the rewinding of the tapes 33 and 34 from the winding reels 36 and 37 are continued.

  Even in this case, before reaching the actual end position of the tapes 33 and 34 to be rewound from the take-up reels 36 and 37, the movement amount of the tapes 33 and 34 detected by the tape movement amount detection unit 74 is detected by the end region detection unit 75. Based on the above, it is possible to detect the end region on the reel mounting end side of the tapes 33 and 34.

  When this end region detecting unit 75 detects the end region on the reel mounting end side of the tapes 33, 34, the motor 57 is stopped, and the winding of the tapes 33, 34 by the take-up drum 35 and the take-up reels 36, 37 are stopped. Stop the rewinding of the tapes 33 and 34. At the same time, it is determined that the end detection units 46 and 47 are abnormal, and abnormal information is output to a higher-level control unit of the banknote handling machine 11 or the abnormality is notified on the display unit of the banknote handling machine 11 or the like.

  The moving amount and moving speed of the tapes 33 and 34 may be detected from the rotation amount of the rollers 38, 39, 40 and 41 around which the tapes 33 and 34 are wound (however, the tapes 33 and 34 and the rollers) 38, 39, 40, 41).

  In the end region detection of the present invention, the detection of the movement amount of the tapes 33 and 34 is not limited to the detection from the rotation amount of the take-up reel 36, but the rotation amount of the take-up drum 35 and the tapes 33 and 34 are wound. The rotation amount of the rollers 38, 39, 40, 41 applied may be detected.

  In addition, the tape position is expressed by counting ± 1 for each predetermined distance, but the position of the tapes 33 and 34 is counted by ± 1 for each predetermined number of pulses using the number of pulses counted by the rotary encoder 65. May be represented.

  In addition, although the tape storage type banknote storage and feeding device 19 that uses two tapes 33 and 34 and sandwiches and stores the banknote 42 between the tapes 33 and 34 is shown, The present invention can be similarly applied to a tape storage type banknote storage and feeding device 19 that stores a banknote 42 between the outer peripheral surface of the winding drum 35 and stores it.

  In addition, as the tape storage type banknote storage and feeding device 19, the two tapes 33 and 34 are used, and the configuration in which the banknote 42 is sandwiched and stored between the tapes 33 and 34 is shown, but one tape is used, The present invention can also be applied to a configuration in which the banknote 42 is sandwiched and stored between the tape and the outer peripheral surface of the winding drum 35.

  In the banknote handling machine, the present invention is used for a temporary storage section that temporarily stores banknotes, a banknote storage section that stores and pays out banknotes, and also handles paper sheets such as checks, slips, and sheets. Used for processing machines.
